[Sheepdog] Sheepdog 0.4.0 schedule and plan

[MORITA Kazutaka]

Hi all,

I think of releasing 0.4.0 at the end of next month, June.

Here is the list of 0.4.0 features which was already implemented:

 - add a new store driver 'farm'
 - add obejct cache support
 - add tracer support
 - add support for variable virtual nodes
 - start sheep daemon as gateway

And here is the list of features which was planed for 0.4.0 before,
but not touched yet:

 - support larger object size
 - use differential copy for fast object recovery
 - add hierarchical zones support
 - reclaim unused objects automatically

I think it is a bit difficult to implement these all.  Any ideas about
which should be dealt with first?  Are there any other features you
want to add?

Other than these features, we need the followings:

 - add more documentations
 - add more test cases
 - improve stability and performance

Please let me know if there is an opinion (about features, schedules,
etc).

If possible, I'd like to release Sheepdog 1.0 as a stable version by
the end of this year.

Thanks,

Kazutaka
